Abstract
Solenoid valve employing a loosely mounted rubber insert in a confining recess of the plunger for sealing an inlet port during closed condition of the valve. In case of adherence at the sealing surface of the inlet port with the rubber insert, initial acceleration of the plunger establishes an inertia impact to effectively break the bond, even at extremely low temperature.
